I was on 75 mg Effexor for about 15 years. I weaned myself off twice, but unsuccessfully because I did not do the bead-counting or weighing procedure. I recently went back on the lowest dose available in capsule form: 37.5 mg. It took about a week to feel ok. My doctor knows little about withdrawal from these meds, so I am thankful for reliable online resources. I have read about the Prozac bridge, but nothing that tempts me to try it. I would suggest you try Effexor to stabilize yourself for the present, and when you are ready, plan a withdrawal method that has a better chance of success for you. Here is one method, from another long-established support group: https://www.survivingantidepressants.org/topic/17671-the-brassmonkey-slide-method-of-micro-tapering/

I should add that my withdrawal experience was similar to yours--after two months of feeling ok, crushing anxiety struck, and fear about every little thing, worse in the morning, slightly better by evening. After two months of that hell, I had enough. I know how to taper off the right way now, so I am optimistic that I can do it when I am ready.
